Bad: "Write a professional email."
Good: "Write a client email about a month-long delay. Here's my usual style:
'Dear [Client], I hope this email finds you well. I wanted to update you on [Project Name]. Unfortunately, we've encountered an issue delaying completion by two weeks. We're working to resolve this and will keep you updated. Please let me know if you have questions. Best regards, [Name]'
Use similar tone for our current supply chain delay situation."
